Checker 2

Notes: This is fairly similar to the first checker. The difference is that this one also has keyboard support which mimics mouse input. Pressing the arrow keys, home and end moves the mouse and pressing space or enter performs the check/uncheck action just like clicking the mouse does. In fact pressing space or enter actually has the program send a mouse click message to itself.

Description: A screenshot of a program in front of a window containing code. The program has a series of horizontal and vertical lines that create a grid. Some of the boxes in the grids have a line going from the upper left corner to the bottom right corner and a line going from the upper right corner to the bottom left corner.
